srEcIFIcATIoN forming part of Letters Patent No. 728,037, dated May 12, 190e:

Application tied oatr 20.1902. serai Itafizma cammen p [0 @ZZ whom, t may concern:

Be it known that I, RUFUS G. STONE, acitizen of the United States, residing at Garden City, in the county of Finney and State of Kansas,have invented a new and usefulTank, of which the following is a specification'.

The invention relates to improvements in tanks.

The object of the present invention is.to

improve the construction of tanks and 'to inv crease their strength, durability, and efciency, and to enable the same to be lshipped in halves and nested together and assembled at their destination.

A further object of the invention is to provide a sheet-metal tank ot this character in which there will be no seam at the angles or corlner edges formed by the bottom and side wa ls.

The invention consists in the construction.

and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying ,drawingaand pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a tank constructed in accordance with this invention. ing one-half of the tank; Fig. Sis a horizontal sectional view.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a tank of hexagonal form; but

it may be constructed of-` any other desired polygonal form; and it consists of la bottom and side walls. The bottomand side walls are constructed of sheet metal, the bottom consisting of inner or central sections 2 and outer sections 3, which are extended and bent at an angle to form wall-sections 4, thereby obviating the necessity of riveting or otherwise securing the bottom to the Walls at the horizontal angle for'med-bysuch parts. The inner or central sections 2 are of semi-Octagonal form riveted at their inneradjacent edges and similarly secured lat their outer edges .to the adjacent ends of the outer sections 3, which are tapered and truncated, as illustrated in Fig. 3. The outer bottom sections 3 are riveted at their adjacent edges, and the Wall-sections are secured together at their Fig. 2 is a similar View show-` vertical edges by rivets 5. The tank is designed to be constructed in halves, as illustrated-in Fig. 2 of the accompanying drawings, to enable them to be nested and conveniently shipped, and in practice the rivets will be mounted at the seam edges to facilitate assembling the parts at theirdestination.

The fupperedges of the wall-sections are bent outward to form projectingtlanges 6 and are secured to an outer frame 7 composed of bars having their ends 8 and 9 recessed at their oppositefaces and overlapped vand secured together. The upper and lowerl faces of the barsare fiush, and the frame, which may be constructed either of wood or metal, may be arrange'don the exterior of the wall-sections, as illustrated in Figs. 1 and 2, or it may be located within'thefsame. l

By constructingand arranging the bottom and wall sections as illustrated in Figs. l and 2 of the'drawings the rivets are arranged at points` remote from the horizontal angles formed vrby the bottom and the walls, and seams at these angles are entirely dispensed with, thereby greatly lessening the cost of construction and,` greatly increasing the .strength and durability of a tank, and there is no liability of the parts separating at these angles or corners, asis the case with tanks having seams at those parts; also, the parts may be assembled with much greater facility than is the case when the bottom and side walls are riveted at the angles formed by them. i l

It will be seen that 'the tank is simple and comparatively inexpensive in construction, that its cost of manufacture is greatly lessened by the particular arrangement of the 'parts and the seams at the adjacent edges of .the same," and that such arrangement also IOO point of unition with the bottom section to a predetermined common circumferential point and bent upward to form side walls.

2. A tank composed of inner and outer sections united at their meeting edges, the bottom being formed by the inner and outer sections conjointly, and the walls formed solely by the outer sections, said inner sections comprising blanks of polygonal form, and said outer sections blanks having their longitudinal edges united to each other and diverging from the point of attachment with the inner sections to a predetermined common circumferential point and bent upward to form the side walls.

3. Atankhaving inner bottom members of polygonal form and side members each comprising a blank having its longitudinal edges parallel for a suitable portion of their length and then converging to form a truncated end united to the bottom members, said side members being bent upward at the point of convergence of their edges to form side Walls and having their meeting edges united.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
